Dear Fluka expert,
I am trying to run a simulation that generates an x-ray field in order to study the skin in interventional radiology and I get the following issues :

I am running FLUKA-4-5.0 with a Mac Mini with MacOS15.5.
I compiled my source.f routine with /path_to_fluka/bin/fff XRay_Field_Generator.f then /path_to_fluka/bin/lfluka -o XRay_Field_Generator XRay_Field_Generator.o and get well my XRay_Field_Generator executable (13.5 Mo).
I compiled FLUKA with gcc14.2.0 installed with MacPort
The command which gcc give me:
/opt/local/bin/gcc
The command gcc --version give me:
GNU Fortran (MacPorts gcc14 14.2.0_3+stdlib_flag) 14.2.0

Could you please help me to find the origin of the issue ?
I attached the files of interest.
